How to Order U-TREASURE Products
We offer three ways to order U-TREASURE products.
1) Visit a U-TREASURE outlet (Shinjuku or Nagoya).
Although the number and kind of product stocks is limited, some products are available for purchase at U-TREASURE Shops as ready-made. Yet, please kindly note that many of our products are “made-to-order”; therefore, it will take certain time to prepare the product after ordering. (Some products may be prepared within a couple of days, but some products may require several months.) If you are interested in purchasing our products at a shop, we strongly recommend that you would contact us well in advance for language and stock availability from the inquiry form. In some cases, you may want to consider placing your order online prior to your visit in order to pick it up at a shop in Japan.
2) Use a proxy purchasing service via U-TREASURE Online Shop.
Currently we are introducing a proxy purchasing service that offers purchase guidance in English or Chinese language for the convenience of overseas customers.
3) Directly purchase at U-TREASURE Online Shop.
You may want to purchase directly from us at U-TREASURE Online Shop especially when you prefer U-TREASURE Online Shop membership point benefits and/or to purchase as tax-free.
